Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed December 12, 1907. Serial No. 406,180.

To all whom it mag concern:

Be it known that I, FRANK lVHITE, a citizen of the United States, residing at New York, borough of Manhattan, county of New York, and State of New York, have invented certain new and useful Improvements in Corner-Beads, of which the following is a specification. v

This invention relates to improvements in corner beads such as are used by plasterers in the construction of plastered walls, and also in the clips or anchor plates for holding such corner beads in position.

The objects of the invention are to provide a clip and a corner bead in which the, clip can be quickly and properly applied to the corner bead without the use of any other instrument than the hands, a so to reinforce and strengthen the corner head at the point of attachment of the clip, and also to so construct the clip that it will hold its position on the bead until it is nailed in position.

Further objects are to provide reliable and substantial corner beads and clips which may be practically used with the least possible expense and trouble.

As is well known, corner beads, sometimes termed corner strips, are used in the construction of plastered walls to form outlines or guides for-the trowel, anchorage places for the mortar, and protection for the finished work where corners, arrises, sweeps, angles, and arches occur.

These being some of the ends in View, my invention consists ofcertain features of construction and combinations of parts to be hereinafter described and then claii'ned, with reference to the accompanying drawings showing a desirable form of the invention, and in which 7 Figure l is a perspective view showing the improved corner bead and its clip or anchor plate applied; Figs. 2 and 3 are transverse sections on lines 22 and 3 3, Fig. 1, respectively; Fig. 4 is a perspective view of the clip or anchor plate, and Fig. 5 is a modified form of corner bead.

Referring to the drawings, the improved corner bead in its preferred form will be found to comprise a metallic strip bent along the longitudinal axis in such wise as to provide a bead aroper or front edge a which may be IOH11( ed as shown or sharper, and longitudin lly extending diverging or spread wings b, each'of said wings being reinforced along the rear portions by means of narrow lips .0, which are bent outwardly and forwardly towards the bead propel-or front edge a, and which are spaced a suitable distance away from the body of the wings. The angle formed by each lip and the contiguous side of the bead is less than a right angle. Such a construction of corner bead provides suitable means for attaching the form of clip disclosed herein and for supporting the corner bead in proper position, without the use of tools. The corner bead may have a cross section similar to Fig. 5.

In the best form of the invention the reinforcing means 0 at both sides extend in substantially diverging planes with the beadproper a at the line of convergence.

The improved clip or anchor plate, shown more particularly in Fig. l, consists of a shank d, two projections c and at one end of saidshankseparated from each. other by means of a gap formed by cutting out the end of the shank, said projections being bent up and formed diversely, that is to say. the projection c at one edge of said shank is bent out of the plane of the shank so that its main portion extending away from the shank will be pa allel thereto, while the other projection has a hookend f which is located on the same side of the shank as is the projection e. Said form, construction and arrangement of the projections c and f, which are the ones preferably resorted to, adapt the clip for engagement with opposite sides of a wing of the corner bead; To engage the clip with the corner bead, the lip portion 0 of the'bead is received in the gap 9 and the clip then turned sidewise causing the hook-end f of projection f to take over the hp 0 at one side of a wing of the bead while the other projection e bears against the opposite side of said wing. The said projections and 7',

when thus interlocked with the reinforce." I

edge of the bead, prevent the bead from being pulled away from the clip and also prevent it from moving laterally in either direction. The inward movement of the bead towards the clip is taken care of and prevented by means of a little spur of metal it which is struck out of the projecting portion f and projects away from the same side of the shank as does the hook f, and forms an abutment for the rear edge of the bead.

When a suitable number of clips such as lOO those herein described are arranged at proper points along the reinforced edges of the improved corner bead, the bead is readyto be set in position by driving nails or passing other, suitable fastenings 2' through holes j previously formed in the clip. Of course it isnot absolutely necessary to form the holes in the clips, but this is the better practice. 1

Obviously other forms of corner bead and .clip within the scope and spirit of my invention will suggest themselves to those skilled, and I do not therefore limit myself to the form, construction or arrangement shown.

Having thus described my invention, what secure .alongthe longitudinal edges in substantially ""diverging planes, with the front bead proper at the line of convergence, the reinforcing means also forming an angle with the contiguous sides of the bead which is less than a right angle. i

3. A corner bead, consisting of a single strip of metal substantially angular in'cross sectionto provide wings, andlips bent up from said wings and extending toward the front bead proper to provide a longitudinal reinforce for each of the Wings, each of said lips forming an angle with the contiguous side of the bead which is less than a right angle.

4. A corner bead, consisting of a strip of metal having a front bead proper and a longitudinal narrow rear lip spaced away from the strip and extending towards the front bead proper, said lip forming an angle with the adjacent side of the bead which is less than a right-angle.

5. A corner bead, consisting of a metallic strip having longitudinally extending spread wings, both of which wings are reinforced on their outer sides, the reinforcing means also forming an angle with the sides of the bead which is less than a right angle, combined with a clip or anchor plate in engagement with the reinforced portions of the bead.

6. A corner bead, consisting of a single strip of metal substantially angular in cross section to provide wings, and n'leans for reinforcing both of said wings on their outer sides, the reinforcing means also forming an angle w'th the sides of the head which is less tlnn a right angle, eombmcd with a clip or anchor plate in engagement with the reinforced portions of the head.

7. A corner bead, consisting of a. single strip of metal substantially angular in cross section to provide wings, and lips bent backwardly from said wings and toward the front bead proper to provide a longitudinal reinforce for each of the wings, said lips forming an angle with the sides of the bead which is less than a right angle, combined with a .clip or anchor plate in engagement with the reinforced portions of the bead.

8. A corner bead, consisting of a strip of metal having a front bead proper and a longitudinal narrow rear'lip spaced away from the strip and extending towards'the front bead proper, said lipforming an angle with the contiguous side of the -bead which is less than a right angle, combined with a clip, or anchor plate in engagement with the reinforced portions of the bead. a

9. A corner bead consisting of a strip of metal substantially angularin cross section to provide Wings, and lips bent up from said wings to provide a longitudinal reinforce for each of the wings, combined with a clip comprising a shank having beyond it separate projecting means positively interlocking with both sides of the reinforced portion of a wing, and an abutment separate from said interlockin means for the outer edge of the saidwing, for substantially the purposes set-,fof'th. l i v. t
